Re: Intel Core i7-4770K Haswell Processor

Text on the retail version is "intel core i7-4770k, sr147", not "intel confidential, qeh6 es". Selected review sample which is unfortunately completely useless for making reviews, but it is good as a desktop processor.

Re: Intel Core i7-4770K Haswell Processor

We didn't observe any heat issues with our sample chip. On our CPU test rig running Prime95, the temperature stabilized at 67C (according to CoreTemp), ambient was 21C, Scythe Kabuto @ 800rpm. Power draw from wall: 149W AC. Is this an engineering sample sent by Intel? Also in the first picture of t...

This looks like a falsely marketed forced convection heatsink.

Natural convection heatsink for 95W TDP would weight 4 Kg and it would be 450mm wide and fins placed 8 mm apart.

Re: HD 7850 reviews

Witcher 2 at ultra settings (ubersampling on) is a rendering farm application. It renders every frame a few times to achieve much better image quality than any regular AA method. Crysis 2 isn't nearly as gpu-heating even without v-sync. W2 power usage is somewhere between peak and maximum.

Re: HD 7850 reviews

7850 maximum power consumption is 101W and 7870 144W, this is felt when playing very GPU heating games (e.g. witcher 2 - other games have lower temps). Since I have 2 cats and can't remove any dust filters or fan grills, I would need new case and larger fans. Larger fan allow much more air to pass s...

Re: Finally a Super Quiet High-end Video Card?

The Sapphire 7850 works better than I anticipated for a non-passive card. At idle it only makes slightly more noise than the other fans, so it's still almost inaudible, and during games it generates a fairly pleasant hum. 7850 noise can be further improved by better arrangement of case fans.
